== Annotate (aka AnnotateModels) {Gem Version}[http://badge.fury.io/rb/annotate] {}[https://travis-ci.org/ctran/annotate_models] {}[https://gemnasium.com/ctran/annotate_models] Add a comment summarizing the current schema to the top or bottom of each of your... - ActiveRecord models - Fixture files - Tests and Specs - Object Daddy exemplars - Machinist blueprints - Fabrication fabricators - Thoughtbot's factory_girl factories, i.e. the (spec|test)/factories/_factory.rb files - routes.rb file (for Rails projects) The schema comment looks like this: # == Schema Info # # Table name: line_items # # id :integer(11) not null, primary key # quantity :integer(11) not null # product_id :integer(11) not null # unit_price :float # order_id :integer(11) # class LineItem < ActiveRecord::Base belongs_to :product . . . It also annotates geometrical columns, geom type and srid, when using +SpatialAdapter+, +PostgisAdapter+ or +PostGISAdapter+: # == Schema Info # # Table name: trips # # local :geometry point, 4326 # path :geometry line_string, 4326 Also, if you pass the -r option, it'll annotate routes.rb with the output of +rake routes+. == Install Into Gemfile from rubygems.org: gem 'annotate', '~> 2.6.6' Into Gemfile from Github: gem 'annotate', github: 'ctran/annotate_models' Into environment gems from rubygems.org: gem install annotate Into environment gems from Github checkout: git clone git://github.com/ctran/annotate_models.git annotate_models cd annotate_models rake build gem install pkg/annotate-*.gem == Usage (If you used the Gemfile install, prefix the below commands with +bundle exec+.) === Usage in Rails To annotate all your models, tests, fixtures, and factories: cd /path/to/app annotate To annotate just your models, tests, and factories: annotate --exclude fixtures To annotate just your models: annotate --exclude tests,fixtures,factories,serializers To annotate routes.rb: annotate --routes To remove model/test/fixture/factory/serializer annotations: annotate --delete To remove routes.rb annotations: annotate --routes --delete == Configuration === Usage Outside of Rails Everything above applies, except that +--routes+ is not meaningful, and you will probably need to explicitly set one or more +--require+ option(s), and/or one or more +--model-dir+ options to inform annotate about the structure of your project and help it bootstrap and load the relevant code. == Configuration If you want to always skip annotations on a particular model, add this string anywhere in the file: # -*- SkipSchemaAnnotations === Configuration in Rails To generate a configuration file (in the form of a +.rake+ file), to set default options: rails g annotate:install Edit this file to control things like output format, where annotations are added (top or bottom of file), and in which artifacts. == Rails Integration By default, once you've generated a configuration file, annotate will be executed whenever you run +rake db:migrate+ (but only in development mode). If you want to disable this behavior permanently, edit the +.rake+ file and change: 'skip_on_db_migrate' => 'false', To: 'skip_on_db_migrate' => 'true', If you want to run +rake db:migrate+ as a one-off without running annotate, you can do so with a simple environment variable, instead of editing the +.rake+ file: skip_on_db_migrate=1 rake db:migrate == Options Usage: annotate [options] [model_file]* -d, --delete Remove annotations from all model files or the routes.rb file -p, --position [before|top|after|bottom] Place the annotations at the top (before) or the bottom (after) of the model/test/fixture/factory/routes file(s) --pc, --position-in-class [before|top|after|bottom] Place the annotations at the top (before) or the bottom (after) of the model file --pf, --position-in-factory [before|top|after|bottom] Place the annotations at the top (before) or the bottom (after) of any factory files --px, --position-in-fixture [before|top|after|bottom] Place the annotations at the top (before) or the bottom (after) of any fixture files --pt, --position-in-test [before|top|after|bottom] Place the annotations at the top (before) or the bottom (after) of any test files --pr, --position-in-routes [before|top|after|bottom] Place the annotations at the top (before) or the bottom (after) of the routes.rb file --ps, --position-in-serializer [before|top|after|bottom] Place the annotations at the top (before) or the bottom (after) of the serializer files --w, --wrapper STR Wrap annotation with the text passed as parameter. If --w option is used, the same text will be used as opening and closing --wo, --wrapper-open STR Annotation wrapper opening. --wc, --wrapper-close STR Annotation wrapper closing -r, --routes Annotate routes.rb with the output of 'rake routes' -v, --version Show the current version of this gem -m, --show-migration Include the migration version number in the annotation -i, --show-indexes List the table's database indexes in the annotation -k, --show-foreign-keys List the table's foreign key constraints in the annotation -s, --simple-indexes Concat the column's related indexes in the annotation --model-dir dir Annotate model files stored in dir rather than app/models, separate multiple dirs with comas --ignore-model-subdirects Ignore subdirectories of the models directory --sort Sort columns alphabetically, rather than in creation order -R, --require path Additional file to require before loading models, may be used multiple times -e [tests,fixtures,factories,serializers], --exclude Do not annotate fixtures, test files, factories, and/or serializers -f [bare|rdoc|markdown], Render Schema Infomation as plain/RDoc/Markdown --format --force Force new annotations even if there are no changes. --timestamp Include timestamp in (routes) annotation --trace If unable to annotate a file, print the full stack trace, not just the exception message. -I, --ignore-columns REGEX don't annotate columns that match a given REGEX (i.e., `annotate -I '^(id|updated_at|created_at)'` == Sorting By default, columns will be sorted in database order (i.e. the order in which migrations were run). If you prefer to sort alphabetically so that the results of annotation are consistent regardless of what order migrations are executed in, use +--sort+. == Markdown The format produced is actually MultiMarkdown, making use of the syntax extension for tables. It's recommended you use +kramdown+ as your parser if you want to use this format. If you're using +yard+ to generate documentation, specify a format of markdown with +kramdown+ as the provider by adding this to your +.yardopts+ file: --markup markdown --markup-provider kramdown Be sure to add this to your +Gemfile+ as well: gem 'kramdown', :groups => [:development], :require => false == WARNING Don't add text after an automatically-created comment block. This tool will blow away the initial/final comment block in your models if it looks like it was previously added by this gem. Be sure to check the changes that this tool makes! If you are using Git, you may simply check your project's status after running +annotate+: $ git status If you are not using a VCS (like Git, Subversion or similar), please tread extra carefully, and consider using one. == Links - Factory Girl: http://github.com/thoughtbot/factory_girl - Object Daddy: http://github.com/flogic/object_daddy - Machinist: http://github.com/notahat/machinist - Fabrication: http://github.com/paulelliott/fabrication - SpatialAdapter: http://github.com/pdeffendol/spatial_adapter - PostgisAdapter: http://github.com/nofxx/postgis_adapter - PostGISAdapter: https://github.com/dazuma/activerecord-postgis-adapter == License Released under the same license as Ruby.
